To all whom it may concern:

Be it known that I, TRUMAN J. Pnn'r, a citizen of the United States ofAmerica, and a resident of Monticello, Jones county, Iowa, have inventedcertain new and useful improvements in Crimping-Machines, of which thefollowing is a specification.

My invention relates to improvements in crimping machines, and theobject of my improvement is to furnish mechanism adapted to'crimp theopen end of a hollow cylindrical body to adapt the latter for use as areceptacle or for other purposes. This object I have accomplished by themeans which are hereinafter described and claimed, and which areillustrated in the accompanying drawings, in which:

Figure 1 is a front elevation of my crimping machine. Fig. 2 is anelevation of the rear of the forward frame part of the ma chine, withthe parts of the machine which are connected thereto sectioned away..Fig. 3 is a like elevation showing certain moving parts in a differentposition. Fig. 4 is a rear elevation of said machine. Fig. 5 is asideelevation of the machine, with parts of the supporting structures'forthe mechanism sectioned away. Fig. 6 is an enlarged detail view of thetwo parallel crimping rollers as employed in crimping a cylindris calbody, and showing the trip-lever about to be operated by the action'ofthe upper crimping roller on the crimped body. Fig. 7 is a perspectiveview ofthe hollow cylindrical body before crimping, and Fig 8 is a likeview of said'body after one end of it' has been crim'ped.

Similar numerals of reference denote corresponding parts throughout theseveral views.

Myv improved device is primarily intended for use in crimping one openend of a hollow metallic cylinder to form the body of 'a' basket orother receptacle.

The supporting frame of my maoh1ne 4 comprises forward and rear cornerstandards 64 and 63. -The standards 64 are fixedly connected in frontbyfa plate 65, and the rear standards 63 are connected in the rearfixedly by a like plate 66. on each side,

the forward and rear standards are connected by'means of side plates 67,said forward, rear 'and side plates extending from the bottom of saidstandards only partly upwardly toward their tops. a 1

A i- L- p d brack t 5 is mounted on the upper part'of the forward plateby means of bolts, and has in its upwardly turned limb a verticalbearing socket in which is rotatably mounted the depending spindle 9 ofthepinion 10 with concaved beveled teeth. On the under surface of saidpinion are crown teeth 11.

Referring to Fig. 5, the numeral 1 denotes a shaft having diminishedparts mounted rotatably in bearing openings in cross-bars between theforward and the rear uprights respectively, and on the rearwardlyextending part of said shaft are fixedly mounted a gear-wheel 6 and thebelt-wheel 7, and also a loosely mounted belt-wheel 8. On the forwardlyextending end of said shaft is removably mounted a longitudinallycrimped forming-head 2 and on the front end of said head is fixed anaxial spindle having an enlarged end 3, said spindle and its enlargedpart being rotatably seated at the'bottom of a T-shapedgroove' in saidbracket 5 so that the forming head and itsLspindle may be dismountedfrom the bracket when desired. On the forwardend of the forming-head. 2is a fixed gear 12 whose teeth mesh with the crown teeth 11 on theconcave pinion 10.

The numerals l6'and 17' denote cross-bars mounted between the forwardstandards 64 and the rear standards 63 respectively. The cross-bar 16has. on its ends (not shown) diminished portions which are seated ingrooves on..the innervertical edges of the standards 64 to allow thecross-bar to be swung upwardly a shortdistance. The rear CI'OSSfbEtI 17is placed between two vertical hangers depending from either end of thecross-bar 18, theends of the latter being diminishedto likewise slide ingrooves on the inner edges of the rear standards 63, and the cross-bar 17 has oppositely extending pintles 62 mounted to rock in bearing socketsin said hangers. A shaft 13 has diminished 'parts mounted in bearingorifices in the cross-bars 16 and.17, and carries on its rearwardlvextending end'a gear-wheel 15meshmg with the gear-wheel. 6, the shaft13' being arranged a little above the other shaft 1. On the forwardlyextending end of the shaft13 is detachably mounted a longitudinallygrooved forming-head 1e adapted to mesh or coact with the forming-head2' when the shaft 13 is moved downwardly. Between the upper ends of theforward standards Stand the rear Standards 63, re-

spectively, are fixed the cross bars 22 and 19. A coiled compressionspring 21 is engaged between the rear cross-bars 18 and 19, about alinedpins 20, and serves to yieldingly push downwardly the cross-bar 18 withits con nected pivotal cross-bar 17 to retain the gear-wheel 15 in meshwith the gear 6. A

tension spring 23 is connected between the,

. meral 35 denotes a medial vertical slot in the lower part of theforward plate 65, and

a pedal lever 34 is passed 'rearwardly through said slot, and has itsrear end pivotally connected to the eye on an eye-bolt 58 mounted in thelower end of the rear plate 66. Referring now to Figs. 2 and 3, in Fig.2is shown the position of the up and down movable roll 13 when disengagedfrom the other roll 1.

The numeral 24 denotes Y a U shaped bar, whose upper endsxare bentforwardly and; secured to theupper edge of the crossbar 16 at oppositesides ofthe roll 13. A swinging arm .25 is pivotally connected at 26 tothe middle of the loop of the U-shaped .bar 24, and has its lower endpivotally connected at 30 to the upper end of the bar 31 whose lower endis provided with a fork 32 which bestrides the middle of the 1ever34,and is pivotally connected thereto by means of a pivot-bolt 33. Aoshortswing-arm 28 has one end pivotedat 27 to the rear face of the plate 65and has its other end pivoted at 29 to the lower part of the w swing-armabove the pivotal connection 30 of .the arm 31 therewith. When the saidsaid rolls from each other.

arms are in the positions shown in said Fig. 2, the spring 23 has 'movedthe cross-bar .16 and U-shaped bar 24 upwardly, disengaging rollsintomesh, the pedal-lever 34 is pushed downwardly thus shifting thepivotallyconnected arms-25, 28 and 31 into overlapping alinement whichplaces them ona dead center and holds the '1'01113 in its loweredposition with the forming-heads 14 and 2 in'mesh. A stop-pin 47 in therear plate 65 prevents the said arms from swinging too far in onedirection.

I have provided mechanism for throwing said armsfrom their position ofdead cen ter to permit the spring .23 to react and draw the former-head14 out of .mesh with the former-head 2. A short rock-shaft 44' ismounted in a bearing orifice in the lower part of the forward plate 65and has arock arm 51 fixed on its forward end/ A short lever 53 ispivotallyflconnected at 54 to the forward part of the frame, and has oneend pivoted to the upper end of a link 52 whose To bringv said 7 of thelever arm is directed between the two forming-heads at one side thereofbut so as to not interfere with their rotations.

Referring now to Figs. 2 and 3, the numeral *denotes a rock-arm fixed inan end of. the shaft 44 and has a tappet body 46 threaded on its freeend. A curved arm43 is fixed on and depends from said shaft 44. Thenumeral 37 denotes aslide-plate having verticalslots'57 for the passageof securing screws 56 on which said plate is mounted to slide up anddown on'the rear faceof the front plate The lower end of the plate 37has an angular foot 39. A vertioal'rod 40 is mounted on the plate toslide up and down in staples 41, with its upper end under and adapted toengage the lower face of the foot 39, 'whenlifte'd. The flowerend of therod 40 has a fork 42 bestriding the end of the curved arm 43. The upperend ofthe slide plate 37 is bent over downwardly .at 38, and said platehas an opening just below thet'ip of this bent-over part.

Referring now to Fig. 5, the nu'meral49 denotesa hand-lever pivoted atits lower end between lugs 48 on the front plate 65. Both the front.plate 65 and the rear plate 66 have horizontally alined bearing openingsin which is movable a slide-rod 36 provided with a notch 59 in its.upper. edge. To the front end of the rod is pivotally con nected thehand lever .49. A belt-shifting arm 61 is fixed on the rear end of therod 36, and a coiled compression spring 60 is mounted on said rodbetween the arm 61 and,

the T6511 face of the rear plate 66, and tends to yielding ly shift therod 36 rearwardly. The upper curved end 38 of the slide plate 37 ridesupon theupper edge of the rod 36,.since said .rod .passes through theopening in said slide-plate.

Operation; The moving parts of the machine being in the inoperativepositions shown in Figs. 2, 3 and 5, when it is desired to operate themachine the pedal lever 34 is depressed, after the u'ncrimped, cylinder68 has been mounted upon the upper forming body 14 This draws the rockarms 25, 28 and 31 into the dead center position shown in Fig. 3,stretching thespring 23 and drawing the roller 13 to its lower position.The

- hand-lever 49 is then swung forwardly causing the shifting-arm 36 toshift a drive-belt,

(not shown), from the loose pulley 8 to the tight pulley 7, whichplaces-the intermeshed gears 6 and 15 in rotationwith their form-1ng-heads 2 and 14, thus crimping the cylinder 68 to the form shown "inFig. 8. When the rod 36 is drawn forwardly to said position, the benttip 38 of the slide plate 37 drops into the notch-59, holding therod inthat position.

Wh en the cylinder 68 is fullyacrimped at 70 the operation of themachine is automatically stopped in the following manner: The fold-overjoint 69 of the cylinder, as

shown in Fig. 6, as the crimping operation is completed, rotates intoengagement with and pushes down the finger 55 of the lever 53 thuscausing the link 52 to rock upwardly the rock-arm 51, rocking the shaft442 to swing the tappet body 46 against the swing arm 31. The arms 28and 31 are then swung oil their dead center so that the spring 23 canreact to rock upwardly the formingrhead 14 so that the crimped cylindermay be dismounted therefrom. Simultaneously, the rock-arm 4E3 pushes upthe slide-rod 40 against the foot 39 on the slideplate 37, thus pushingup the slide-plate and disengaging its bent-over end 38 from the rod 36so that the spring may react and shift the driving-belt back upon theloose pulley. I I

It is to be understood that various changes may be made in the forms,arrangement and operation of the coacting parts of my machine, withoutdeparting from the principles of the invention or the scope of itsprotection.
